| Abstract | The TISPAN group from ETSI is currently working on the specification a Next Generation Network (NGN), based on the IP Multimedia Subsystem (IMS) as the service control architecture. This NGN provide a extensible platform that supports the delivering of next generation multimedia services with QoS requirements over multiple access network technologies. Nevertheless, the QoS solutions developed by TISPAN in the first release of specifications for the NGN are mainly focused on the access network, and QoS coverage is not provided for the core network and the residential environment, where the end user terminals are located. In this paper a proposal is presented to extend the TISPAN QoS solution to the residential environment, by means of a Residential Gateway (RGW). This RGW will process the signalling messages that are exchanged between the end user terminals and the Core IMS in the NGN, performing an adequate QoS resource management within the residential environment. Several signalling scenarios are presented, covering the cases related to the establishment and release of multimedia sessions within the TISPAN NGN. For each case, the procedures executed in the RGW in respect to the signalling and QoS management are detailed. |
